FORM TIE FOR CONCRETE STRUCTURES Filed Oct. 8, 1928 Patented May 5, 1931UNITED STATES PATENT' 'QFFICE JOSEPH L: WEBER, OF GREEN BAY, WISCONSIN,ASSIGNOR TO WEBER-MCDONALD WALL TIE CGMPANY, A CORPORATION OFVJISCCIN'SIN FORM TIE FOR CONCRETE STRUCTURES Application filed October8, 1928. Serial No. 310,987.

; tion of a wall, curbing, siding or foundation,

can be temporarily connected at opposite sides of the mold, so that onthe hardening of the structure, the sections can be convenientlyreleased, without damage to the mold and also without excessive exertionon the part of mechanic, thereby enabling the dismantling of the moldwith dispatch.

Another object of the invention is the provision of means of thischaracter, wherein the construction thereof is novel in form, requiringlike fasteners for all ties used in connection with the mold or form,these fasteners being easily accessible, so as to permit quick andconvenient removal of the sections of the mold or form, when thestructure has become set.

A further object of the invention is the provision of means of thischaracter, whlch is extremely simple 1n construction, thorou 'hlreliable and eflicient' in )ur ose strong, durable, readily and easilyapplied and removed from a form or mold, standard in character, andinexpensive to manufacture.

\Vith the above and other objects in view the invention consists in thefeatures of conments of the invention, and pointed out in the claimhereunto appended.

In the accompanying drawings:

Figure 1, is a fragmentary plan view of a pair of form sides betweenwhich a concrete wall is to be formed, showing one form of a tieconstructed in accordance with the invention applied.

Figure 2, is a vertical cross section taken approximately on the line2-2 of Figure 1.

Figure 3, is a view similar to Figure 1,

showing a slightinodification of the invention.

Figure 4:, is a vertical cross section taken approximately on the line44 of Figure 3. Figure 5, is a view similar to Figure 1', showing afurther slight modification of the invention.

Figure 6, is a vertical cross section taken approximately on the line6+6 of Figure 5.

Figure 7, is a side view of the tie shown in Figure 1.

Figure 8, is an end view thereof.

Figure 9, is a side view of the tie shown in Figure 3. c

Figure 10, is an edge View thereof.

Figure 11, is a side View of the tie shown in Figure 5.

Figure 12, is a edge view thereof;

Figures 13, 14, 15, and 16, are detail views of a still furthermodification of the invention.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail, the form or mold within which theconcrete Walls or the like are to be molded is comprised generally oftwo sides A, and B, respectively, formed by boards or the like tiedtogether with spacing members C, located at intervals, which spacingmembers are under compression when the forms or molds are drawn togetherby the ties herein after fully described.

With reference to Figures 1, 2, 7, and 8, of

the drawings,the tie thcreinlshown comprises a a pair of bails, eachincluding a straightrun of wire 10, havlng the required length andrigidity, formed at one-end portion with a right angular terminal 11,provided with an eye 12, while the other end portion is formed with anoutwardly distorted terminal 13, provided with an'eye extremityl l.:These bails are reversely applied about the spacing members C, andbetween the meeting edges of the boards of the sides A, and B, as isclearly ship, and passed through said eyes 12, and 14:,

are nails 15, which are driven into the spacing members C, as shown.

In Figures 3, 4, 9 and 10, of the drawings there is shown a slightmodification of tie, wherein each bail includes an intermediate angularportion 16, and outer non-aligned stralghtportlons 17, one of the latterbeingv formed with a hook terminal 18, provided with an eyeentremity 19,and the other with a right angular terminal 20, having an eye extremity21. These bails are reversely applied to the form or mold, so thatthehook terminals 18, embrace partially the spacing members C, and theright angularterminals 20, overlap the outer edge portions of saidmembers, as clearly shown in Figures r3, and 4, of the drawings. Engagedin the eye extremities 19, and 21, are nails 22, these being driven intothe spacing members C.

With reference to Figures 5, 6, 11, and 12,

oft-he drawings, there is shown a further modification of tie, whereinthe hook terminals 23, and 24, are reverselyset, and formed with eyeextremities 25, the latter receiving nails 26, which are driven into thespacing members C, when the bails are applied as shown in Figuresf), and6, of said drawings.

It should be apparent that when. the form or mold including the sides A,and B, and the spacing members C, are confined within a trench beneaththe ground surface, the ties can be readily released by removalof thenails from the eyes, and such nails are readily accessible to anextractor operated at the ground surface.

WVith reference to Figures 13, 14, 15 and 16, of the drawings there isshown a still further modification of the invention, wherein each bailthere bein two as com aanionsQ coin- V b prises a stralght run 2(,having right/angular terminals 28, one belng formed with an eyeextremity 29, while the other is. formed with a hook bill 30. In the'useof the bails, these are reverselydisposed in the pair, so that the bill30, of each'will be inserted in the eye extremity 29, thus removablyinterlocking the pair togetherifor embracing relation to the worksimilarto Figures 1, and 2, of the. drawings.

Whatis claimed is A form tie of the kind described, comprising a pair ofrelatively stiff-wire members,

each includinga long stretch and relative short bent terminals, theterminals being constructed 'to embrace a wall form, and eyes formed onthe terminals and adapted to receivefasteners to be driven intothe wallform to hold said terminals in embracing relation thereto, said eyes ofthe respective terminals being free of each other and non-twistedtogether, the: long stretches of the members being adapted toliecrosswise of the wall form.

In testimony whereof I afiixmy signature.

JOSEPH L. VEBER.
